The Shared DNA
Book of Dead was deliberately designed in the spirit of Book of Ra, then the most popular land-based slot in Europe. Both games feature: an Egyptian adventure theme, a 5×3 reel grid, 10 paylines, a book symbol that acts as both wild and scatter, and a free spins round where one randomly selected symbol expands. The mechanics are nearly identical at a structural level.
Key Differences
RTP: Book of Dead at 96.21% significantly outperforms Book of Ra's standard 92.13% RTP (the higher 95.13% version exists but is less common online). Over a $1,000 session this difference is $40 in expected value.
Max Win: Both games offer a 5,000x max win from 5 top symbols on a payline. In Book of Dead this is Rich Wilde; in Book of Ra it is the explorer symbol.
Availability: Book of Ra is primarily associated with Novomatic-powered casinos and older platforms. Book of Dead is available at virtually every major online casino through Play'n GO's wide licensing network.
Graphics: Book of Dead uses modern HTML5 with crisp animations and dynamic sound. Book of Ra, especially in its original form, uses older visual design from the mid-2000s. Book of Ra Deluxe and newer variants have improved visuals but still lag behind Book of Dead's production quality.
Which Should You Play?
For online play, Book of Dead is the clear choice based on RTP alone. The 96.21% vs 92–95% gap is meaningful over time. Both games deliver the same core experience — long waits for free spins, followed by an expanding symbol reveal that determines the bonus value. If you enjoy one, you will enjoy the other. But for the best mathematical return, Book of Dead wins.
